I am running Ubuntu 12.04 on my computer. Yesterday I tried to change the splash screen according to the instructions here here.Then I installed gdm. After that I restarted the computer and the splash screen was changed. I enabled automatic login. Then I restarted again and went into windows 7 and again came back to Ubuntu.
This time Ubuntu was stuck up at a black screen with the following message:

                                    Ubuntu 12.04

I have reinstalled Ubuntu now, but I just want to know what caused the problem.

[23.359845]usb 1-1.5:device descriptor read/64, error -32

This is a hardware error you see it with some USB device. Is at random as it could get.

USB has an over-current protection, which gets triggered when power consumption from the port is too high. (Triggering this error)

You can try unplugging all devices and trying again after a minute or two.

I tried by removing all USB devices but Ubuntu didn't start. – M.Tarun Sep 5 '13 at 12:11
@M.Tarun then the underlying issue wasn't the USB, but since you reinstalled we will never know. Anyways, I edited your question so it will be on the scope of the answer I was going to give: what the message means, not why the system didn't boot. – Braiam Sep 5 '13 at 12:14
When I pressed the power button it said stopping TiMidityALSA++ emulation and killed all processes and then turned off. – M.Tarun Sep 5 '13 at 12:21
If you have such problem, this could be a BIOS bug resolved by upgrading BIOS. – MarkoGamma Jul 3 at 14:57
